RJS - Insert_html and visual_effect at the same time

Hello,
there is any way to add a partial using insert_html using visual_effect
to do it?
(inset_html and visual_effect at the same time.)

I want to do something like:

render :update do |page|
page.insert_html.visual_effect :bottom, :invoice_items, :partial =>
“invoice_item”, :object => InvoiceItem.new, :BlindDown
end

thanks,

David S.
